GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 369,693, dated September 13, 1887.

Application filed January 26, 1884. Renewed February 23, 1887. Serial No. 228.622. (No model.)

To all whom, it may concern.-

Be it known that I, CHARLES COLAHAN, of Cleveland, county of Ouyahoga, and State of Ohio, have invented certain new and useful Improvements in Grain-Binders, of which the following is a specification.

My invention relates to that class of automatic grain binders in which the binding mechanism is started by the pressure of a predetermined quantity of grain against a coinpressing and tripping arm and of that form of construction known as the Appleby Binder, the object of my invention being to dispense with many of the parts used by said Appleby in the use of the compressing arm or fingers; and my invention consists in securing and releasing the rock-shaft and its link and arm connections and placing fixed cam projections at or near the heel of the binderarm center of revolution or axial bearing, and said cams are so located as to be in the path or line of travel of the heel of the supporting-bar on which said compressing-fingers are mounted, so that the heel or inner end of said bar may be forced on its pivotal support or fulcrum on the heel of the binder-arm as said binder-arm vibrates on its axis and causes the said bar to traverse around its center of motion and carry the heelextension of said bar in contact with said camsurfaces and force said bar to rock and close its compressing-fingersin the process of finally compressing the sheaf while the cord is being tied, and on the opening of said arms for the release of the bundle the reverse movement causes the heel of said bar to be brought in contact with other cam projections and forces the heel end of said bar down,and thus carries the tripping and compressing fingers to the proper place to stop the inflowing grain as it accumulates for the next sheaf or bundle. This movement of said bar also carries the rockshaft-and link connection and its supportingcrank to the desired position to sustain the thrust of the inflowing grain, and by being locked orsustainedin a fixed position by means of a simple pawl or stop which will admit of the desired movement of the tripping and compressing arms as said compressing arms are actuated by the movements of the cord-carrying or binder arm, and said compressing-bar will rock on its fixed linksupport, which is similar to the devices used for this purpose shown in Patent No. 212,420, differing there from in the point or fact of dispensing with application of power to the supporting-crank, as shown in said patent, and myinvention consists in the operating of the compressing-fingers by the heel of the binder-arm. While the supporting-bar may be free to rock on. its supporting-link connections,it is securely locked in its place while compressing the bundle,and said supporting-bar may be released at the proper moment to admit the discharge of the bound bundle.

In said Patent No. 212,420 the supportingbar is forced down by the saniecrank used by me, being rocked by its pitman connection, this pitman-connection also serving to support the connecting-link in a fixed position, the said bar, and its tripping and compressing fingers, during the accumulation of the grain, when it aids in forcing it forward in the compression of the bundle. 1 deem this pitmanconnection unnecessary in the operation of compressing the grain in connection with the binder-arm attachment and the stationary or fixed cams cast on the main frame to cause the compressing and tripping fingers, as the same are sustained by the supporting-bar and its linlcconnections as the binder-arm actuates the same and causes it to move in a desired course, as said fixed cams force the heel of said bar to Vibrate or rock said bar on its pivot.

In the drawings, Figure 1 represents a transverse section ofa binding attachment embodying my invention as it appears in readiness to receive the grain as it is packed therein in the usual manner. Fig. 2 is a similar sectional view with the binder-arm and compressingfingers in position of compressing the bundle while it is being bound. Fig. 3 shows a similar view of the position of the parts as the bundle is being discharged. Fig. 4 is a detail View of the crank-supporting arm and its ratchet and double pawl that lock and sustain the same, as hereinafter fully explained.

A represents the binder'arm; A, the heelextension of same. A is the main-frame casting or support and journal of the binder-arm shaft B. O-represents the tripping and compressing fingers. D represents the supporting bar of said fingers. E is the link connecting thecrank F thereto. fis its shaft or pivotal support. G is the ratchet-elbow, which is a part of the crank F. Said ratchet is of sector form, and is locked in its raised position, as shown in Figs. 1 and 2, by the pawl H, which pawl is pivoted at d. I is a pawl-tripping finger, which is pivoted on the same pivot, d, as the pawl H. Said pawl and supplemental tripping-finger are held in position by springs c and e. the tripping of the pawl H when the heel of the binder-arm is brought in contact with its pawl-tripping finger I on its reverse movement. at and a are can'i-surfaces on the main frame casting A.

In operation it will thus be clearly observed by those experiencedin the art that, as illustrated in Fig. 1, the infiowing grain will be received against the tripping and compressing fingers O in the usual manner, and on the moving up of the binder and compressing arms, when the same shall be caused to start by the operation of the tripping device, the supporting-bar D, which is supported by its link E and locked arm F in its present position,resting with its heel D against cam a, will be caused by the downward movement of the heel of the binder-arm to rock in on its vibrating link E, and by being brought in contact with the cam a at its heel will be caused to rock the compressing-fingers up against the bundle as desired. it passes by the pawl-tripping finger I, will cause said finger to rock on its pivot cl out of the way, and not disturb the pawl H, and on the completion of the bundle and the reverse movement of the arms A O D to permit discharge of the bound sheaf, it is important to drop the outer arm and its fingers quickly, and as the arm A is forced back by its shaft the heel projection A will come in contact with c is a stop on pawl H, and will cause The heel A of the binder-arm A, as

ratchet-quadrant G onarm F, which will cause said arm F to drop, carrying with it the link E and the supporting-bar D and its fingers C, and thus the bound bundle is permitted to be discharged without meeting any obstruction or delay, and as the binder-arm is being forced down reachesits lowest position. Its heel end will cause the end D of the supporting-bar D to engage the cam a, and cause the arm D and its fingers O to rise to their place and carry the link E and its crank F to a proper posi tion, and the spring-pawl H will lock and retain the same until another bundle is formed.

Having thus fully described my invention and its operation, what I claim, and desire to secure by Letters Patent, is-

1. In an automatic grain-binder, the combination of the binder-arm A, having the heel A, pivoted to the supporting-bar D. having the heel D, and the fixed cams on a, operating as and for the purposes substantially as shown and described.

2. The combination of the arm A, having the heel A,and the supporting-bar D, having the heel D, and being pivoted to the heel A, the tripping and compressing fingers O, and the cams a a, opera ting substantially as shown and described.

3. The combination of the bar D, its ex tended end D, pivoted at A to binder-arm A. the lug a on the main frame, with the arms E F and pivofif, and means, substantially as de scribed, for looking the bar D and its compressing-fingers as the bundle is forming.

4. The combination of the main frame A, the shaft B, the binder-arm A, secured to the shaft B, the compressor-bar D, pivoted at A to a heel of the binder-arm,.and a lug or cam, a, on the mainframe A, substantially as set forth.
